Real Home Value Calculator: Assessed Value vs Market Value

Understanding your home’s true market value is about more than pictures, software assessments, and price-per-square-foot. Whether you’re a current homeowner thinking of selling or are house-hunting, it’s crucial you understand what factors affect home valuation. By partnering with a local market expert, sellers will avoid pricing their house out of the market (the kiss of death in real estate) and buyers will ensure they get a good deal on their next home.

So, how do you accurately calculate a home’s value? After all, the value a home is assigned by its town or county and the one it’s given when it’s listed are often dramatically different from one another. Which one is accurate and what does it all mean? Read on to learn more.

Assessed Value vs Market Value: What’s the difference?

When it comes to home value, you’ll often hear two terms:  assessed value and market value

A home’s assessed value is often the lower number of the two, and is the value given by your municipality or county. Investopedia defines assessed value as “the dollar value assigned to a property to measure applicable taxes.” Although property tax laws vary, assessors commonly arrive at this number by taking into account the following:

A home’s market value, or Fair Market Value, is the price a buyer is willing to pay or a seller is willing to accept for a property. A skilled real estate professional will arrive at the value using a variety of metrics, including:

What Determines a Home’s Value?

You’ve likely heard the motto of real estate: “Location, location, location.” This means a home’s value relies on its location. While the home and structures on the property will likely depreciate over time, the land beneath it tends to appreciate.

Why? Land is in limited supply and a growing population puts increased demand on the housing supply. As a result values increase.

Other factors that affect your home’s value include the function and appearance of the property, how well the home and other structures are maintained and whether the home is a lifestyle property, such as a ranch style with mountain views or beach bungalow.

Ultimately, the best indication of a home’s value is the overall supply and demand of the market. This is why we recommend you partner with a real estate professional who takes all of these factors – the assessed value, local market conditions, home features, and has physically walked through and experienced your home – into consideration to determine the most accurate market value.

How to determine if a property is comparable to yours

Both assessed value and market value are partially determined by the sales price of similar, or comparable, homes in the area. To determine if a home is comparable to yours, look for the following characteristics:

While you may not find a home with the same exact characteristics as yours, you’ll likely find a few that are close. To account for any disparity, adjust the sales prices of the comparable properties.

Look at the differences between your property and the one in question and determine if the differences increased or decreased the sales price and by how much. For example, if your home has two bathrooms and a similar home only has three, estimate how much did that extra bathroom increased the sale price of the similar home? The adjusted sale price is the estimation of what the property would sell for if both properties were exactly the same.

Where can you find comparable sales?

Fortunately, you can find comparable home sales in a variety of places:
